With the growth of the consumer income level and the progress of low carbon economy, electric cars are gradually entering the life of the general public. Electric vehicle charging stations are bound to become a significant point of development for the automotive and energy industries. 

According to China National Development and Reform Commission (NDRC), there are1.22 million EV charging stations in China by the end of 2019. And it is expected to expand 200,000 more for public use and over 400,000 more as private use.

In addition to EV charging station revenue itself, what can really make a huge impact for EV enterprises is actually the control of the energy industry. In the U.S., 2019, Tesla CEO Elon Musk says the company's energy division, Tesla Energy, is becoming a distributed global power company that may even grow beyond its automotive business. Musk believes that Tesla will continue to deploy more solar and energy storage systems in homes and on the grid, and manage these distributed systems to make it a massive power supply company.

In big cities, many families have at least one car. And with that comes the growing difficulty of parking and charging in the city. To address these issues, three-dimensional parking is a good solution. A complete EV parking system requires the integration of many systems, includes power, control, e-commerce & data platform, user interface, and communications. ADTEK Multi-Loop Meter AEM-DRA is a compact and powerful offer for such integration needs for all kinds of charging station manufacturers and system integrators.

Project Name: Jiujiang Hai Yun Beach Smart 3D Parking

System Integrator: in south China

Project brief：

Jiujiang Haiyun Beach Smart 3D Parking occupies an area of 15201.38 square meters, with a total construction area of 16318.78 square meters, and an investment of about 60 million RMB. It includes 900 parking spaces and 90 charging stations.

Electric car users need to pay for electricity in the charging station. To this end, the construction of a corresponding charging billing system and the introduction of a centralized information management platform are an important part of this project.

AEM-DRA is very suitable for multiple loops in EV power system

AEM-DRA multi-circuit meter is designed for multi-loop applications: up to 24 loops in single-phase or 8-loops in three-phase, DIN35mm rail-mounted, LCD display. It provides power data and Time-Of-Use (TOU) data, with pulse output, RS485 and Ethernet communication. It has the advantages of compact size, high precision, good reliability and easy installation. For system integration, it is a very competitive product for centralized monitoring and communication.

AEM-DRA’s function in EV charging station power system:

◆    EV charging station is a small power charging device of 7KW. It is equipped with a power quality testing device to test the power quality of the entire power supply circuit of charging station.

◆ Electrical fire control devices are installed in each charging station incoming circuit.

◆ A miniature circuit breaker or contactor is installed in the charging side to control the charging time.

◆ AEM-DRA multi-loop power meter is combined with a charging management controller, which is responsible for power and billing control in centralized monitoring system. The energy data is read by this controller through the RS485 communication port of the rail-mounted AEM-DRA.
